Help me pick my sheave set up I wanna order today or tomorrow

2006 rhino 660 as far as i know stock cam and piston, HRC long travel kit, PWR over sized oil cooler and radiator, full alba exhaust, k&n with outterwears, jetted, dyna tek cdi, high volume fuel pump, i run 27" big horns on a 12" wheel, next tire will be a 26", I pretty much ride trails and have to cross a 1ft deep mud hole here and there i dont ride thru long passes of mud.
I wanna slug the wet clutch and buy the complete sheave kit with the spring, washers, ect I just dont know what gram weights to order, what color spring, or if i should do grease or greaseless

14gr and a orange is good all around...14gr and a purple if you want it aggressive in the woods but it wouldnt be good for road ridn
